Abstract (en)
[origin: EP1926049A1] The method involves receiving volumes of cameras (1-3) in different directions, and carrying out a rough calibration of a position of the cameras relative to each other and the volumes by determining a volume mapping equation. A correction factor (dx 1, dy 2) is calculated for the mapping equation from a difference between camera image coordinates so that a point is identical with another point by the corrected mapping equation for the camera. The corrections are carried out for particles in a volume.
